Not able to use a partitions in Ubuntu

I am not able to copy or extract files to, and even create new folder in the a partition that I have.I am able to copy files to and do other things in the other two partitions but not in the third one. What to do? I have attached some screenshots for reference. Pl. help ASAP. Thanks in advance :)

You are working with Linux. Linux handles security through file ownerships and permissions. For file systems that support linux permissions, the permissions of the root folder are in effect. By default, owner is the administrator: root, and currently on Ubuntu, the permissions by default are +rwx for user, +rwx for group and +rx for others.

If you want to use the drive fully for your current user, then change the permissions of the mount point:

sudo chown $USER:$USER /media/aaditya/15e16d9b-fbe1-4d51-ade6-2d7b4e2F9a86

You see that I retrieved the information on where this drive is mounted from your screenshot.

Some advice not directly connected to the specific question (with thanks to a comment of Oldfred)

• It is advisable to label the drive, so it is automounted with an easy recognizable name.
• If this is an internal drive that you use frequently, you better create a mount point and have it automatically mounted during startup by including it in /etc/fstab.
